Research 477: DESIGN – Detection of Environmental Sources of Infectious Disease in Groundwater Networks

In Ireland groundwater sources provide domestic drinking water to approximately 750,000 people in mainly rural areas. Studies that differentiate the exposure pathways and sources are of paramount importance for establishing environmental management solutions that safeguard public health. Ireland currently has the highest incidence of verotoxigenic Escherichia coli (VTEC) infection in the EU, domestic private wells are identified as a likely source of infection. This is a public health concern for public authorities and consumers alike. The DESIGN research project provides the first quantitative assessment of VTEC and Cryptosporidium in domestic groundwater supplies in Ireland. It provides insight into the prevalence, source and transport of VTEC and Cryptosporidium in groundwater supplies. The research developed bespoke, spatio-temporal groundwater management policies, and offers invaluable guidance for future planning, remediation and mitigation of contamination in private wells.
